Manual Workflows
Engineers spend weeks on repetitive CAD tasks that could be automated — drawing tables row by row, routing cables manually, counting components by hand.
Design utility-scale solar farms with AI precision and engineering control.
From site boundary to EPC-ready CAD output — deterministic engines, AI assistant, one Civil 3D plugin.

The Problem with Solar Design Today
Hidden Assumptions
Black-box tools hide engineering assumptions. When results seem off, there is no way to trace back through the logic or validate intermediate steps.
Fragmented Tools
Layout in one tool, electrical in another, shading in a third. Data is re-entered, errors compound, and no single model holds the full design truth.
VibeSolar unifies layout, electrical, civil, shading, and financial analysis into one deterministic pipeline — from site boundary to EPC-ready output in minutes, not weeks.
How It Works
Import Your Site
Load a DXF boundary, fetch terrain from public APIs, or draw directly in Civil 3D. VibeSolar builds the 3D terrain model automatically.
Configure & Generate
Select equipment, set constraints, and generate a complete design — layout, electrical, civil, and shading — in one click or one sentence.
Review & Iterate
Run AI design review, compare scenarios, adjust parameters. Every change recomputes the full pipeline in seconds.
Export & Deliver
Export EPC-ready CAD files, PVSyst-compatible shading scenes, Bill of Quantities, financial reports, and string plans.
Powerful Features for Every Stage of Design
Terrain-Aware Layout Generation
- Fixed-tilt and single-axis tracker placement with automatic configuration detection
- Multi-direction sweep optimization (N-S, S-N, E-W, W-E) — picks best by capacity or target kWp
- Automatic gap filling with sub-type generation (e.g., 3x27 → 3x18 + 3x9)
- Terrain-aware table splitting when slopes exceed equipment limits
- Buildable area computation with setbacks, exclusions, and corridor reservations
Complete Electrical Design
From Strings to Substations
- String assignment with MPPT row-grouping constraints (no mixing top/bottom rows on same MPPT)
- K-means inverter placement with cluster-balanced loading
- IEC 62548-1 compliant string calculator with temperature-corrected voltage limits
- Manhattan-routed DC/AC cables with 3D terrain following and configurable burial depths

Civil Engineering
Roads, Fencing, Grading

Cloud Twin, WebUI & Automation Agent
- Every project gets a cloud twin — access your designs from any device, anywhere
- WebUI Access: upload DXF through browser, generate layouts without Civil 3D license
- Automation Agent: monitors a workspace folder, sends jobs to backend automatically
- RESTful API with 161 endpoints — integrate VibeSolar into any pipeline
- Server-Sent Events streaming for real-time progress visualization
- Checkpoint & resume: crash recovery without recomputing from scratch
- Feature flags system — 12 runtime-configurable flags let administrators enable/disable capabilities per deployment. Control scenario analysis, ML learning, streaming behavior, and more via environment variables.
Explore Hundreds of Design Scenarios in Minutes
- Generate 1-50 design variants by sweeping pitch, tilt, setback, and gap ranges simultaneously
- Compare equipment options — test multiple module models, inverter types, and mounting configurations side by side
- Automatic yield estimation with latitude-based GHI proxy and LCOE calculation (EUR/MWh)
- P10 / P50 / P90 capacity percentile rankings with uncertainty quantification and confidence scoring
- 7 optimization strategies: balanced, maximum density, low earthworks, max yield, min LCOE, maintainability, schedule-safe
- Fully deterministic — each scenario runs the same layout engine, just with different parameters. Reproducible via seed control.
- Results ranked with composite scoring across density, earthworks, yield, and financial metrics
- Probabilistic models for high-uncertainty inputs — terrain variability, irradiance deviations, energy price fluctuations, and module degradation curves are captured through ensemble analysis rather than single-point assumptions
A System That Learns How You Design
VibeSolar observes how you refine generated layouts — which tables you move, which cables you reroute, which inverters you reposition. This creates a learning layer that understands your design preferences and organization standards.
How it works:
- Every edit you make after layout generation is captured as a structured event (move, delete, rotate, resize, reroute — 10 action types across 11 object classes)
- Semantic diff engine groups low-level edits into meaningful changes: 'Removed 3 tables in NW quadrant', 'Moved 2 inverters 8.5m south'
- Rule-based intent inference identifies WHY you made the change — 7 intent categories from hidden hard constraints to aesthetic preferences
- Confidence scoring (0.4–0.8) on every inferred intent — the system knows what it's sure about and what needs confirmation
What's live now (Stage 1):
- ✓ Edit event capture across all layout objects
- ✓ Semantic change grouping with human-readable descriptions
- ✓ Intent inference with 7 rule-based patterns
- ✓ SQLite telemetry store with full session history
- ✓ 6 dedicated API endpoints for telemetry
- ✓ Feature-flag gated — enable per deployment
What's coming next:
- → Stage 2: Prediction — edit hotspot heatmaps, acceptance likelihood scoring
- → Stage 3: Reranking — learned preferences influence scenario variant ranking
- → Stage 4: Suggestions — proactive layout adjustment proposals
Privacy: All ML data is opt-in, organization-scoped, and never leaves your instance unless you explicitly enable analytics sharing.
